Step 1: Nitrogen Fixation Believe it or not, lightning and bacteria are primarily responsible for turning atmospheric nitrogen into nitrogen living things can use, in a process called nitrogen fixation. Atmospheric nitrogen (N2) is very stable, so it takes an incredible amount of energy to conve...
Nitrogen gas is the most abundant gas in the atmosphere. Why is it not useful to most organisms in its atmospheric state? Explain what would happen to an ecosystem if the decomposers disappeared. How do nitrogen-fixing microbes first become associated with their symbioti...
These results from Fennoscandia clearly show that the rate of N addition is crucial for responses of forest growth. Consistent with the point stressed by Bebber (2021), very high rates of N addition cannot be relied upon for understanding likely effects of atmospheric N deposition. Much ...

The thin layer of gases that envelops the Earth is held in place by the planet's gravity. Dry air consists of 78% nitrogen, 21% oxygen, 1% argon and other inert gases, carbon dioxide, etc.; but air also contains a variable amount of water vapor. The atmospheric pressure declines ...

Therefore, the cumulative effects of altered atmospheric deposition as well as ozone have the potential to stimulate or depress soil organic matter and nutrient pools over time. Nonnative and Invasive Species Species invasion is a global phenomenon that causes eco- logical and economic damage to ...
Some people use the term ‘atmospheric pollution.’ This type includesthe release of particulates and chemicals into the atmosphere. Particulates are microscopic liquid or solid matter that float in the air. The letters PM, when talking about air quality, stand for ‘particulate matter.’ ...
